SPECIFICATION forming part of Letters :Patent No. 632,696, datedSeptember 12, 1899. Application filed November '7, 1898. Serial No.695,647. (No model.)

To all 'wh/ont it may concern.-

Be it lrnown that I, KARL BUXBAUM, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Bicycle-Pumps, whichimprovement is fully set forth in the following speciiication andaccompanying' drawings.

My invention consists in providing a bicycle with a pump for iniiatingthe tires thereof, a portion of the frame thereof constituting thebarrel, which also guides the handle of the piston-rod, the novelfeature being pointed out in the claims that follow the speciiication.

It also consists of a novel construction of said handle whereby it maybe readily applied and removed, as desired.

Figure l represents a side elevation of a bicycle-pump embodying myinvention. Fig. 2 represents a vertical section of a portion thereof onan enlarged scale. Fig. 3 represents a horizontal section of a portionon line o: a', Fig. 2. Fig. 4 represents a perspective view of detachedportions.

Similar letters of reference indicate corresponding parts in the gures.

Referring to the drawings, A designates the frame of a bicycle, which,excepting the feature of my invention applied thereto, is of usualconstruction. The member B of said frame is adapted to constitute thebarrel of a pump, for which purpose it is provided with the piston C,(shown in dotted lines,) the piston-rod D, the handle E, and the nippleF, the latter being adapted to have attached to it a tube, which maybeconnected with the valves of the tires for inating the latter. Inopposite sides of the member B are vertical slots G, in which the handleE has its play, it being seen that by raising and lowering or operatingsaid handle as usual in pumps the piston will receive its motions,andthe handle is guided by the walls of said slots. The handle isadapted lto be removed from the pistonrod when service of the same isnot required and may be carried elsewhere, as desired. For this purposeI provide the stock of said handle, at or about the center thereof, withthe jaws II and J, the jaw II being preferably stationary, but the jaw Jis mov ble, it being` retained and guided in an opening in said stockand adapted to advance toward and rel cede from the jaw II. The member Kof the handle is fitted to said stock and held thereon by suitablescrew-threads, it being adapted to contact with the jaw J at the backthereof and press the same toward the jaw II, it bein g seen that whenthe handle is passed through the slots of the frame thefaces of thejaws, which are recessed, are placed over the end of the piston-rod,which end is shaped to cause said faces to take iirm hold thereof. Thenthe member K of the handle is screwed or pushed in,whereby it pressesthe jaw J against the rod and, with the jaw II, causes the handie to betightly connected with said rod, when, as is evident, the pump may beoperated. By unscrewing or withdrawing the member K the jaw J will berelieved of pressure, and the handle is then free to be removed from thepiston-rod and withdrawn through the slots of the frame. In order tofacilitate the outward motion of the jaw J and fully set it back fromthe jaw II, it is provided with the pin L, which is passed through slotsM in the stock of the handle, serving also to guide said jaw J andprevent turning of the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In a bicycle-pump, a handle for the piston-rod, provided with jaws,one of which is movable, a member of said handle bein g adapt ed tooperate the movable jaw and hold it engaged with said rod, and a pin onsaid jaw, the stock of the handle having a slot in which said pin isreceived and guided.

2. A bicycle-pump having its barrel constitute a member of the frame ofa bicycle, a piston in said barrel, a rod connected with said piston, ahandle for said rod having a removable member, and jaws on said handle,one of which is movable, said jaws being adapted to engage with saidrod, said member having a slot for said handle in its motions and saidhandle having its movable jaw adapted to be controlled by said handlemember.
